Just received an email from Lan Airways mentioning they are having a big sale on their flights from Sydney to Santiago,Chile.
Flights from 1,399 return. Travel period is from April to September 2015 (there may be blackout dates).
They also are offering codeshare services from Melbourne (around $1,500) , Brisbane (around $1,500) and Perth (around $2,000). All via Sydney.
Then from Santiago, there are connections to all latin destinations.
I've flown on this airline and route multiple times.
Lan Chile is a great airline… close to Qantas in terms of service. This route now uses brand new Dreamliners (Qantas uses its aging 747's).
Argentina is the ultimate destination for the OzBargainer, due to their currency crisis. You can easily get 13 Argentine Pesos for $1 USD on the streets of Buenos Aires), which is an amazing exchange rate (Google "Blue Dollar"). It's easy and fairly safe. The official exchange rate is 8.60 Pesos for $1 USD… so you get 50% more money, for FREE !!!!
In fact, you can actually make money by buying Argentine Pesos using the "Blue Dollar" in Calle Florida in Buenos Aires, and sell the Pesos to the National Australia Bank back in Australia. It's crazy!!!
EDIT: I just added an example in the forums about how to turn AUD$100 into AUD$106.43 using this method (https://www.ozbargain.com.au/node/181151)
